Well, that was easy.
They rolled me into the cardiac cath lab at 0825 and I was back in the recovery room at 0905. They found no blockage which is a great relief. I need to watch my cholesterol and we need to determine why I get dizzy when my HR goes over 175 or so but, with a family history of heart issues and atherosclerosis, it's great to have confirmation of no blockage and confirmation of no structural issues.
